The 40-year-old definitely looked like she could fit right in with the MTV "Jersey Shore" kids!

But we’ve seen this dress before – probably because Britney Spears wore the same getup for her first day of "The X Factor!"

The pop star sported the hot pink Lichtenberg dress for the first round of open auditions in Austin, Texas. Spears completed her outfit with black YSL pumps and wore her hair in wavy curls.

To be honest, this isn’t out favorite look on either celebrity, and we’re not really fans of the sheer panel trend that’s taken over Hollywood.

But if we have to pick one – we have to give it to Britney! The dress it doesn’t look as revealing in the chest area and bright pink for the pop-princess seems fitting … we’d just like to see different shoes next time.
